Description

A kind of novel compound combined electrical equipment
Technical field
The utility model relates to a kind of novel combined combined electrical apparatus; be specifically related to the complete semi-enclosed high voltage switchgear system of a kind of control for power plant, power station, factory's controller switching equipment and railway electrification equipment, measurement, protection, isolation and switching, belong to technical field of electric control.
Background technology
Existing open type high-voltage electrical equipment is based on circuit breaker mostly, is connected between device with the aerial bus of exposure by isolating switch, earthed switch, current transformer, simple combination together.All elements are traditional type product, intelligent, degree of miniaturization is not high.
Common compound combined electrical equipment adopts separate-box type to design mostly, and product three-phase is independent module, so often brings the shortcomings such as the volume of product is excessive, and sealing part is many, cost is higher.
Utility model content
For the problems referred to above, the utility model provides a kind of novel case compound combined electrical equipment altogether, its object is to: reduction equipment volume, minimizing sealing part, reduces equipment cost, adapts at present to device intelligence, miniaturized requirement.
Technical solution of the present utility model:
A kind of novel combined combined electrical apparatus, comprising: entry/exit thread casing, isolating/grounding switch, current transformer, SF 6circuit breaker, LCP cabinet, is characterized in that: adopt Threephase common-box design, A, B, C three-phase conductor is integrated in one and fills specified SF 6in the seal casinghousing of gas pressure, each functional unit is arranged in seal casinghousing by inserting mode and is connected by bus, and described functional unit is with novel SF 6circuit breaker is main, is made up of, at SF isolating/grounding switch, current transformer 6on the left of circuit breaker, (outgoing line side) is provided with isolating/grounding switch, outlet casing tube; Right side (inlet wire side) is provided with isolating/grounding switch, entrance bushing, current transformer.
Described entry/exit thread casing adopts composite insulator.
Described bus is the built on stilts bus of open type.
Described current transformer is electronic current mutual inductor or electromagnetic-type electronic instrument transformer.
The beneficial effect of utility model:
The utility model adopts Threephase common-box design, and be divided into A, B, C three-phase, three-phase conductor is integrated in one and fills specified SF 6in the seal casinghousing of gas pressure, each functional unit is arranged in seal casinghousing by inserting mode and is connected by bus.Common compound combined electrical equipment can be solved by adopting said structure and adopt separate-box type design (namely product three-phase is independent module), the volume of product is excessive, be unfavorable for the shortcomings such as the miniaturization of the equipment that realizes, sealing part is many, cost is higher; Employing Threephase common-box designs, and both can realize the electric blocking of equipment, can realize mechanical latching again, prevent misoperation, the safe operation of better guarantee equipment; Because each electric elements are by being in SF 6interior conductor connects, therefore not by the impact of environment.Can be used in High aititude, high filthy environment.Bus is open type, and therefore gas consumption greatly reduces, and easy access, and interruption duration shortens greatly.Insulator adopts composite insulator, and lightweight, anti-soil anti-sudden strain of a muscle ability is strong.Both can install traditional type product, and also can install electronic type product, intelligent product degree is higher.
Accompanying drawing explanation
Fig. 1: be the utility model planar structure principle schematic.
Wherein: 1. entry/exit thread casing; 2. isolating/grounding switch; 3. current transformer; 4. underframe; 5. SF 6circuit breaker; 6. LCP cabinet.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further:
The novel combined combined electrical apparatus of one as shown in Figure 1, comprising: entry/exit thread casing 1, isolating/grounding switch 2, current transformer 3, SF 6circuit breaker 5, LCP cabinet 6, adopt Threephase common-box design, A, B, C three-phase conductor be integrated in one and fill specified SF 6in the seal casinghousing of gas pressure, each functional unit is arranged in seal casinghousing by inserting mode and is connected by bus, and described functional unit is with novel SF 6circuit breaker is main, is made up of, at SF isolating/grounding switch 2, current transformer 3 6on the left of circuit breaker, (outgoing line side) is provided with isolating/grounding switch 2, outlet casing tube; Right side (inlet wire side) is provided with isolating/grounding switch 2, entrance bushing, current transformer 3, described entry/exit thread casing adopts composite insulator, described bus is the built on stilts bus of open type, and described current transformer 3 is electronic current mutual inductor or electromagnetic-type electronic instrument transformer.
Employing Threephase common-box designs:
1. can solve common compound combined electrical equipment and adopt separate-box type design, product three-phase is independent module, the problem that the volume of product is excessive, realizes the miniaturization of equipment;
2. can solve common compound combined electrical equipment and adopt the shortcomings such as separate-box type design sealing part is many, cost is higher;
3. Threephase common-box design, both can realize the electric blocking of equipment, can realize mechanical latching again, prevent misoperation, the safe operation of better guarantee equipment.
As shown in Figure 1, this novel combined combined electric appliance equipment adopts modularized design, and each functional unit standardized module is produced, and adopts the connected mode of grafting between functional unit, and it is simple, convenient to install.In factory, complete the assembling of main element, Whole Equipment interval is transported, less in substation field installment work, greatly improves the operating efficiency of field operation.
This novel combined combined electrical apparatus is made up of parts such as circuit breaker, current transformer, isolating/grounding switch, entry/exit thread casing, LCP cabinets.Current transformer can select electronic current mutual inductor or electromagnetic-type electronic instrument transformer as required.The element such as lightning arrester, voltage transformer can be installed additional, also can install the intelligent element of external additional and make it possess the feature of "smart" products.
The design of this product modular, can according to the different designs needs of transformer station, each functional unit of combination in any, to meet the various mode of connection of user.
